A Doylestown Township man who allegedly reported an attempted carjacking during the Monday night manhunt for killer Bradley Stone was charged Friday with making a false report and creating a false alarm.

Luke S. Sanderlin, 34, told police shortly after 7 p.m. Monday that he was walking his dog when a man wearing camouflage stopped him and demanded his car keys, police said. His false report diverted police resources to central Bucks County, county District Attorney David Heckler said Friday.

Heckler said Sanderlin lied to "call attention to himself."

"We are fortunate, and it is no thanks to anything about Sanderlin's conduct, that no direct harm resulted from this farce," he said.

Bucks County and Doylestown Township detectives found several holes in Sanderlin's claim that a man fitting Stone's description jumped him but fled after Sanderlin's dog bit the attacker and Sanderlin fired his handgun three times, according to Sanderlin's arrest affidavit.

A Montgomery County detective said he saw Stone's corpse and it had no dog bites, the affidavit says.

"We are still counting the costs in taxpayers' dollars wasted by Mr. Sanderlin," Hecker said. "There is no accounting for the emotional stress felt by many Central Bucks residents as a result of the alert and lockdown which the police were forced to call as a result of Sanderlin's hoax."

Sanderlin was arraigned by District Judge Mark Douple on charges of making a false report, reckless endangerment, risking a catastrophe and creating a false alarm. He was sent to Bucks County Prison under $250,000 bail.

Stone, 35, of Pennsburg was law enforcement officials' principal suspect Monday night in the deaths early that day of his ex-wife and five others in Montgomery County. He was last seen alive wearing camouflage.

"The defendant [Sanderlin] was aware of the multiple homicides and ensuing manhunt in Montgomery County and sought to use these events to call attention to himself," Heckler said. "Authorities learned that the defendant had been engaged in an unsuccessful endeavor to raise money for himself to obtain treatment for an alleged neurologic disease."

The false report brought in police from Bucks, Montgomery and Philadelphia counties, and resulted in the lockdowns of area homes, the Central Bucks Family YMCA, Doylestown Hospital and Central Bucks West High School, police said.

Stone's body was found Tuesday afternoon in Upper Hanover Township, not far from his home in Pennsburg. Authorities are still investigating how he died.

Sanderlin told a Bucks County 911 dispatcher Monday that the purported man in camouflage was carrying a knife when he approached Sanderlin near Burpee and Shady Retreat roads in Doylestown Township, police said.

"A guy just jumped me out of the woods wearing fatigues," he told the dispatcher, according to the arrest affidavit.

Sanderlin said the man knocked him down and demanded his keys, but then his dog, Major, bit the attacker and Sanderlin fired three shots at the man, the affidavit says.

"The only reason I have my gun on me is … I heard all the stuff going on earlier today," he said, referring to the six homicides, according to the affidavit.

Detectives found three bullet casings at the scene, but the rest of Sanderlin's story quickly fell apart, the affidavit says. He later said he always carries a handgun.

A neighbor told detectives that Sanderlin's wife, Elizabeth, talked last week about making up a story to draw public attention to his need for a $20,000 surgery, the affidavit says.

Among Sanderlin's contradictory statements, he said he was blinded by his muzzle flash and could not describe his attacker, then said his attacker resembled Stone, and then said his attacker looked "exactly like" Stone, according to the affidavit.
